Apple 145B manual Using a RAM disk, Creating a RAM disk

Using a RAM disk

A RAM disk is a portion of your computer’s memory that you set aside for use as a temporary storage device. Using a RAM disk conserves power because the computer uses less energy to access RAM than to access a hard disk or a floppy disk.

To use a RAM disk, you should have at least 4 MB of RAM in your computer because memory assigned to a RAM disk is not available for opening programs.

Choosing Sleep or restarting the computer does not affect a RAM disk—but if your computer has a built-in floppy disk drive, choosing Shut Down erases the contents of the RAM disk (but does not remove the RAM disk itself ).

Remember a few precautions if you use a RAM disk:

mBefore using a program on a RAM disk, test the program on your hard disk or a floppy disk to make sure that it works properly with your computer.

mDon’t store your only copy of a file on a RAM disk. Keep a backup copy on your hard disk or a floppy disk.

Creating a RAM disk

1.Choose Control Panels from the Apple (K) menu.

2.Open the Memory control panel.

The RAM disk portion of this control panel is at the bottom of the window. If your computer has less than 3 MB of RAM, this portion does not appear.
